CONTROLLED LOW TEMPERATURE TESTS OF SPROUTED SEEDS AS A MEASURE OF COLD HARDINESS OF WINTER WHEAT VARIETIES

Abstract

Twenty winter wheat varieties were tested for cold hardiness in the sprouted seed stage. Their relative cold hardiness at this stage was in close agreement with their relative cold hardiness in freezing tests of young plants and with their field winter hardiness. Testing by the procedure outlined is apparently a reliable method of testing for cold hardiness. It permits the testing of a large number of varieties in a limited space.
